FIG. 1 is a schematic flowchart illustrating a method for regulating communication parameters according to an embodiment of the present disclosure. The method may be executed by network equipment or terminal equipment. As illustrated in FIG. 1, the method 100 includes the following operations.

In S110, a first equipment establishes a communication with a second equipment according to preset configurations of communication parameters.

In S120, the first equipment regulates the configurations of one or more of the communication parameters according to a network state and/or service state in a communication process.

In S130, the first equipment sends communication parameter regulation indication information to the second equipment, the communication parameter regulation indication information indicating a result of regulation performed by the first equipment on the configurations of the one or more of the communication parameters.

In such a manner, according to the method for regulating the communication parameters in the embodiment of the present disclosure, network equipment, or terminal equipments serving as two parties communication with each other may dynamically regulate the configurations of the communication parameters according to the network state and/or service state in the communication process, so that performance and applicability of a wireless communication system are improved.

It is to be understood that, in the embodiment of the present disclosure, the first equipment may be a network equipment, and the second equipment is a terminal equipment, or the first equipment is a terminal equipment and the second equipment is another terminal equipment.

Optionally, as illustrated in FIG. 2, the method may further include the following operations.

In S140, the first equipment receives processing capability indication information sent by the second equipment. The processing capability indication information may indicate that the second equipment is capable of communicating with the first equipment by using the same parameter with different configurations.

That is, the first equipment may regulate the communication parameters according to the network state and/or service state in the communication process only when determining that the second equipment is capable of communicating with the first equipment by using the same parameter with different configurations. In other words, in the embodiment of the present disclosure, in the same subcarrier/cell, different communication parameters may be used in time-frequency resource blocks allocated for different users, and therefore transmitters and receivers of the first equipment and the second equipment are required to have capabilities in processing multiple communication parameters simultaneously, and the equipments may be classified into different types according to capabilities of the equipments in simultaneously processing different parameters.

Furthermore, the second equipment may report, in an attach process after random access, a capability in communicating with the first equipment by using the same parameter with different configurations. For example, the second equipment may send an attach request message to the first equipment. The attach request message including the processing capability indication information. The second equipment may report a capability in a random access process. For example, the second equipment may contain capability data in a random access message. The second equipment may further report the capability to the first equipment according to equipment capability query information sent by the first equipment after the first equipment transmits the equipment capability query information. However, the present disclosure is not so limited thereto.

Optionally, in S110, the communication parameters are multiple access manners for communication and/or basic physical layer parameters corresponding to the multiple access manners. For example, the multiple access manners for communication may be Orthogonal Frequency Division Multiplexing Access (OFDMA)/Single-carrier Frequency-Division Multiple Access (SC-FDMA) and derivative multiple access manners or other multiple access manners probably to be used in a future communication system. Basic physical layer parameters corresponding to the OFDMA/SC-FDMA and derivative multiple access manners may include at least one of a subcarrier spacing, an OFDM symbol length, a Cyclic Prefix (CP) length, a sampling frequency, a reference signal density and pattern configured for purposes of channel estimation, demodulation and the like, a sequence construction of a reference signal and a resource window granularity.

That is, the network equipment, or the terminal equipments serving as the two parties communicating with each other may regulate the configurations of one or more of the parameters according to the network state and/or service state of a communication network where the network equipment and the terminal equipments are located. For example, the subcarrier spacing, the OFDM symbol length, the CP length, the sampling frequency, the reference signal density and image may be increased or decreased according to a practical requirement, wherein the reference signal density and image are configured for the purposes of channel estimation, demodulation and the like. For example, a relative motion between the two parties communicating with each other may cause a Doppler frequency shift. The Doppler frequency shift is greater if the relative motion is faster. For ensuring correct demodulation, it is necessary to increase the subcarrier spacing and simultaneously increase the reference signal density. A change in a channel environment may cause phenomena such as delay spread, angular spread, propagation loss, penetration loss and the like. In addition, when a propagation environment is more complicated, when there are more obstacles, and when sizes of the obstacles are larger, transmission delay spread is greater. In such case, the CP length needs to be increased. The network equipment or the terminal equipments serving as the two parties communicating with each other may regulate the sequence construction of the reference signal according to the practical requirement. For example, the network equipment or the terminal equipments serving as the two parties communicating with each other may regulate a sequence function for generating the reference signal from a quasi-orthogonal sequence to a pseudo-random code, a Zadoff-Chu sequence or the like. The network equipment or the terminal equipments serving as the two parties communicating with each other may also regulate the resource window granularity (i.e. minimum sizes of a resource window on a frequency domain and a time domain) according to the practical requirement.

Optionally, in S110, the preset configurations of the communication parameters may be default configurations. In other words, the communication parameters may be default parameters. For Device-to-Device (D2D) communication, the terminal equipment may broadcast the default parameters through a discovery channel. And different frequency bands and different geographical regions may have different default parameters.

Moreover, optionally, in S110, the preset configurations of the communication parameters may be configurations predetermined by the two parties communicating with each other in the random access process. Specifically, the network equipment or the terminal equipments serving as the two parties communicating with each other may determine the preset configurations of the communication parameters according to at least one of: condition of a wireless channel transmission between the first equipment and the second equipment, communication capabilities of the first equipment and the second equipment and a service type for which the second equipment initiates random access. The first equipment sends the preset configurations of the communication parameters to the second equipment after determining the preset configurations of the communication parameters.

Optionally, the first equipment may also obtain the condition of the wireless channel transmission between the first equipment and the second equipment from random access information initiated by other equipment instead of the second equipment before the communication is established with the second equipment. Alternatively, the first equipment may further acquire the condition of the wireless channel transmission between the first equipment and the second equipment from data and signaling sent by the equipment which has communicated with the first equipment, or from channel state indicator information fed back by the equipment. The communication capabilities of the first equipment and the second equipment include, but not limited to the number of transmitting and receiving antennas, transmitted power, receiving sensitivity, and a bandwidth used for communication.

Specifically, the network equipment or the terminal equipments serving as the two parties communicating with each other may determine configurations of the communication parameters when the terminal equipments accesses the communication network for the first time, according to information such as the channel condition obtained by random access sequence estimation, a determined distance between the two parties communicating with each other and a type of a service for which the terminal equipment initiates random access. For example, in the random access process, the network equipment may decide to allocate a frequency band for a certain piece of terminal equipment to use according to a service requirement or other information. And the frequency band may be or may be not a frequency band where the terminal equipment initiates random access.

Optionally, the first equipment may send the preset configurations of the communication parameters to the second equipment by containing the preset configurations of the communication parameters in a random access response message. The first equipment may also send the preset configurations of the communication parameters to the second equipment by sending another message containing the preset configurations of the communication parameters to the second equipment.

Optionally, in S120, the network state may include at least one of: a channel environment between the first equipment and the second equipment, a load and interference of a communication network where the first equipment and the second equipment are located, a requirement of an application on a data rate, and a requirement of the application on energy consumption.

Specifically, when the network state changes in the communication process, the network equipment or the terminal equipments serving as the two parties communicating with each other may regulate the configurations of the communication parameters in real time. The network state may change due to a change of the channel environment between the terminal equipment and the network equipment (for example, a base station in service and a neighbor base station) or due to a change of the terminal equipments serving as the two parties communicating with each other, for example, due to a channel change caused by the frequency band used in the communication process, antennae and mobility, or due to a channel environment change caused by mobility of the terminal equipments serving as the two parties communicating with each other. The network state may also change due to changes in load and interference of the network. The network state may also change due to changes in the requirement of the application in the network on the data rate and/or the requirement of the application in the network on the energy consumption. However, the present disclosure is not limited thereto.

In the embodiment of the present disclosure, optionally, the network equipment or the terminal equipments serving as the two parties communicating with each other may perform measurement by itself to obtain the network state and/or the service state. The network equipment or the terminal equipments serving as the two parties communicating with each other may also receive state information reported by the terminal equipment or the other terminal equipment serving as one of the two parties communicating with each other, and may acquire the network state and/or the service state according to the state information.

Optionally, S120 may specifically be implemented as follows: parameter regulation request information for requesting regulation on the configurations of one or more of the communication parameters is received from the second equipment; and the one or more of the communication parameters are regulated according to the parameter regulation request information.

That is, when a service is initiated by the second equipment or the service changes or a wireless signal environment changes, the second equipment may apply to the first equipment for parameter regulation. Optionally, the second equipment may send request information to the first equipment to request communication parameter regulation. The first equipment measures the network state by itself after receiving the request information. For example, the first equipment may judge whether the network state has changed or not according to quality of received data sent by the second equipment. Alternatively, the first equipment may judge whether the network state and/or the service state has/have changed or not by receiving a state report indicating the network state and/or the service state from terminal equipment of the same type with the second equipment in the communication network, and determine the specific communication parameters to be regulated. The first equipment may notify the regulation result to the second equipment after completing regulation.

Furthermore, a handshaking mechanism may be adopted for parameter regulation. That is, the first equipment is required to send Acknowledgement (ACK) information indicating an ACK of successful reception of the parameter regulation request information (for example, a reply may be given with an ACK frame), after receiving the parameter regulation request information sent by the second equipment. If the second equipment fails to receive from the first equipment a response to the parameter regulation request information within predetermined time period, the second equipment may resend the parameter regulation request information to the first equipment, or the second equipment may communicate with the first equipment still by adopting the configurations of the communication parameters which are used before applying for parameter regulation. The first equipment may receive and transmit information by using regulated and unregulated parameters.

Optionally, S120 is specifically implemented as follows: state information, which may indicate the network state and/or the service state may be received from the second equipment; and the configurations of one or more of the communication parameters may be regulated according to the state information.

Specifically, the second equipment may report the network state and/or the service state, for example, a channel quality change (a measurement result of the abovementioned Doppler frequency shift, transmission loss, the delay spread and the like or a channel quality indicator quantified by the measurement result), to the first equipment. The first equipment actively regulates the communication parameters and notify the regulation result to the second equipment, after receiving the network state and/or service state reported by the second equipment. The second equipment may regularly or irregularly report the network state and/or the service state to the first equipment, which will not be limited in the present disclosure.

Furthermore, the second equipment may report the network state and/or service state measured by itself to the first equipment and at the same time may send the parameter regulation request information applying for communication parameter regulation to the first equipment. After receiving the parameter regulation request information, the first equipment regulates the communication parameters according to the network state and/or service state reported by the second equipment, and notifies the regulation result to the second equipment.

Optionally, the first equipment may send the parameter regulation indication information to the second equipment through a physical layer control channel. For example, there may be multiple Radio Resource Control (RRC) connections between the two parties communicating with each other. Different RRC connections may have different communication parameters. Regulation of the communication parameters of each connection (carrier or base station) may be notified to the second equipment through a common physical layer control channel (i.e., a physical layer control channel shared by multiple connections), or an independent physical layer control channel for this connection. The physical layer control channel may be a new physical downlink control channel.

Alternatively, the first equipment may notify the parameter regulation result to the second equipment through a channel such as a paging channel or a broadcast channel. However, the present disclosure is not limited thereto.

Moreover, the first equipment may send only the regulation result of the regulated communication parameters to the second equipment. The first equipment may also send all of the regulated and unregulated communication parameters to the second equipment. Furthermore, the regulation result sent by the first equipment may be represented in form of an absolute value, or in form of a relative value. For example, it is assumed that the subcarrier spacing before regulation is 15 kHz. For weakening influence of the Doppler frequency shift on correct demodulation of a signal, it is necessary to increase the subcarrier spacing. In such case, the first equipment may directly notify the second equipment that the regulated subcarrier spacing is 20 kHz, or notify the second equipment that the regulated subcarrier spacing is 5 kHz larger than the unregulated subcarrier spacing. There are no limits made in the present disclosure.

In such a manner, according to the method for regulating the communication parameters in the embodiment of the present disclosure, the network equipment or the terminal equipments serving as the two parties communicating with each other may dynamically regulate the communication parameters according to the network state and/or service state in the communication process, so that the performance and applicability of the wireless communication system are improved.
